JAMES D.V ATTEBERRY, OF WIRT, OKLAHOMA.

PUMP.

p Application led March 6, 1924. Serial No. 697,409.

To all whom t may concern: Y

Be it known that I, JAMES D. ATTEBERRY,

a citizen of the United States, residing at` be discharged therefrom,` at selectedinter-v vals, without the necessity of raising orloweringy the outer tubing. v

A further object of the invention is to V provide means ofthe above mentioned character, which are simple 1n constructlon, .strong and durable.

' Other objects and advantages of the invention-will Vbe apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout. the same. 4

Figure 1 is a side elevation of apparatus embodying my invention, parts being shown in central vertical longitudinal section,

Figure 2 is an enlarged central vertical section through the lower end of the working barrel and elements carried thereby.

' Figure 3 is` a similar view through the sand releasing valve and associated elements,

Figure 4 is a transverse section taken on line 4 4 of Figure 1, i l

Figure 5 is a similar view on line 5 5 of F1gure 1, and,

Figure 6 is asimilar view on line 6-6 of Figure 1. y

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates the outer casing ortubing of the well, which is sunk in the ground to the desired depth. The upper third of this casing is apertured as indicated at 11, whereby the oil or water, having the sand in suspension therein, may enter this outer casing.

The numeral 12 designates a sand trap casing, preferably screw threaded upon the lower end of the outer casing 10. This sand trap casing has a downwardly tapering opening 13, adapted to be normally closed by an upwardly seating valve 14, and engaging a shoulder l5. The valve 14 operates within a cage16, having large openings 17 formed therein, so that the sand may discharge readily therefrom. ,The cage embodies a lower casing section 18, having a plug or bushing .19 screw threaded into its lower end. This plug or bushing has a cen,- tral opening 20 slidably receiving a rod 21, which carries the valve 14.` This rod is surroundedby a suitably heavy compressible coil spring 21, serving to move the valve 14 upwardly against its seat. 'A tubular extension 22 is screw threaded to the `plug or bushing 19, as indicated at 23, and the rod `Y`,21 projects intothe same. The lower end of the tubular extension 22 is closed by a plug y24, having screw threaded engagement therewith. As clearly shown .in Figure 1, the cage and 14 associated elements are located in the bottom portion 25 of the well.

The numeral 26 designates the working barrel, which is screw threaded or otherwise attached to the lower end of the inner tubing. This working barrel receives the umping means, which may be of any well own or preferred type. Attached to the lower end of the working barrel 26, as by means of the coupling 27, is a perforated inlet pipe 28, to the lower end of which is attached, by means of thc coupling 29 or the like, a sand settling tube 30. This sand settling tube hasits lower end closed by a plug 'or cap31, having screwthreaded engagement therewith, and this plug or cap carries an, upwardly projecting detlector 32, preferably integral therewith. This deflector tapers upwardly and may be conical or of any other suitable shape, and is arranged concentrically within the sand settling tube 30. Surrounding the deflector 32 are outlet openings 33, preferably triangular, and increasing in` width downwardly.

Attached to the lower end of the plug or cap 31, by means of a screw threaded engagement, is a sand ejecting lunger 34, the lower end of which is tapered) or rounded.

In operation, the outer casing or tube is lowered into osition within the well, and is supported 1n such position by any suitable means. The working barrel 26 with its tube which carries it, is of course lowered into the outer casing or tube, with the plunger 34 spaced a suitable distance from the sand releasing barrel 14. The usual pumping means is arranged within the working barrel. The oil or water with the sand in ll() l l tain length of-time, vsuch as two orfthree` suspension'4 therein, passes through the upper,

apertured portion ofthe outer casing or tubing, and then downwardly, prior to entering the perforated intake pipe or tube 28. Durf ing this downward movement, considerable of the sand held in suspension separates out from the oil or water, by virtue of' its vheavier'specific gravity, and settles in the lower'portion of the outer casing or tubing 10, above the valve 14. Some of the sand enters the intake tube 28, and separates out from the oil or water, by gravity, and will discharge into the sand settling tube 30 from which it Ipasses through the openings 33 into the bottom of the casing or tubing 10. After the pump has been operated for a cermonths, it will be found that the sand has accumulated inthe bottom of the outer cas`- ing or`tubing 10, to such an extent as to'iu- .terfere' with the roper operation of the pump, and when t is occurs, the outer tubing 1() remaining stationary, the working i barrel and its inner tubev is lowered and the plunger' 34 strikes the'sand and forces it downwardly through the opening 18, such sand opening` the valve 14, which allows the sand to discharge into the auge 16. The- -sand now passes through t e.openings 18 and is collected in the bottom of the well. `The working barrel and inner tubing are of course subsequently raised to the desired elevation. I` is thus seen that the plunger 34 serves to'mechanically hammer or force the sand downwardly and outwardly through the'opening A18, and this down- 'i wardly moving sand opens the sand'releasing 'valve 14'. 1

It is to be understood't that the form'of my invention herewith shown and' described "is to be taken as a preferred example of the same, and that variouschangesin the shape,

size, and arrangement of parts, may be resorted to, without departing from the spirit of .my inventionyor the scope ofthe subjoined claims. l Having thus described my invention, I claim: j

1. A pump of the character described, comprising an outer tubing, a' valve structure secured to the lower end oit the Outer tubing-and embodying an upwardly seating spring-pressedv valve, 'an' inner tubing mounted w1th1n the outer tublng and adapted to be raised and lowered therein and embodying'a working barrel and an apertured inlet tube, anda sand ejecting plunger secured to the inlet tube and adapted to contact with the sand and force the sand downwardly fromk the outer tubing by first open ing said valve.

2. A pump of the character described comprising, an` outer tubing 'having a por- `tion thereof apcrtured, a valve structure secredto the lower end of.r` the outer tub.

ing and embodylng an upwardly seating valve adapted when' opened to permit of the discharge of sand fromrthe outerltubing, a spring to normally hold the valve seated, an inner tubing embodying a working barrel and apertured part, saidiapertured part having an extension to mechanically engage the sand within-the bottom ofthel outer tubing andforce the same downwardly against the upwardly seating valve for opening the valve and discharging the sand. p'

3. A pump of the character described, comprising an outer tubing having a portion thereof apertured, a valve structure secured to the lower end of the outer tubing and embodying an upwardly seating :spring-pressed valve, an inner tubing, a working barrel secured to the inner tubing, an apertured pipe secured to the working barrel, asettling tube secured to the apertured `pipe and provided upon its sides with outlet apertures, an upstanding delector mounted within the lower end of the settling'tube, and a plunger secured to the lower 4endof the settling tube and projecting therebelow and adapted for mechanical contact with the sand to force,
